The present invention relates to a crusher for crushing branches of tree, and more specifically, to a crusher comprising power transmission units which transmit power of the engine to a cutter which cuts and crushes the branches in pieces, wherein each of the power transmission units includes: a connection unit having a connection shaft fixated to one side of a body, and a connection pulley inserted to the connection shaft to rotate; a first power transmission unit having a driving pulley inserted into a driving shaft of the engine to rotate and a first driving belt connecting the driving pulley and the connection pulley; a second power transmission unit having a cutter pulley inserted into a rotation shaft of the cutter and a second driving belt connecting the cutter pulley and the connection pulley, and thus the power transmission through the belt can be performed effectively. Also, the present invention can prevent loss of power due to looseness of belts, reduce loads to the belts, thereby durability of the belts can be extended. |
